What is LittleFinger ransomware? And how does it implement its attack?

LittleFinger ransomware is a data-encrypting Trojan which was first spotted at the end of May 2018. Based on the preliminary analysis conducted by security experts, this new ransomware threat is a new addition to the HiddenTear ransomware family. Though its code may be based on this open-source platform, LittleFinger ransomware is not a typical HiddenTear variant as it is different in some ways and further analysis also revealed that developers of this threat may have used some code snippets of HiddenTear in developing it as opposed to making a customized copy.

Once it infiltrates a targeted computer, it will initiate a connection to its remote Command and Control server where it sends some data about the infected system. It is also where this ransomware gets its additional malicious files that help it in implementing its attack on the infected computer. It starts its attack by searching the computer for files with the following formats:

.3dm, .3g2, .3gp, .7zip, .aaf, .accdb, .aep, .aepx, .aet, .ai, .aif, .as, .as3, .asf, .asp, .asx, .avi, .bmp, .c, .class, .cpp, .cs, .csv, .dat, .db, .dbf, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .dwg, .dxf, .efx, .eps, .fla, .flv, .gif, .h, .idml, .iff, .indb, .indd, .indl, .indt, .inx, .jar, .java, .jpeg, .jpg, .js, .m3u, .m3u8, .m4u, .max, .mdb, .mid, .mkv, .mov, .mp3, .mp4, .mpa, .mpeg, .mpg, .msg, .pdb, .pdf, .php, .plb, .pmd, .png, .pot, .potm, .potx, .ppam, .ppj, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .prel, .prproj, .ps, .psd, .py, .ra, .rar, .raw, .rb, .rtf, .sdf, .sdf, .ses, .sldm, .sldx, .sql, .svg, .swf, .tif, .txt, .vcf, .vob, .wav, .wma, .wmv, .wpd, .wps, .xla, .xlam, .xll, .xlm, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .xqx, .xqx, .zip

After it finds the above mentioned file formats, it will apply the AES encryption algorithm in locking the files and appends the .0x3737451845184518 string on each one of the encrypted files, signifying that they are encrypted by LittleFinger ransomware. Once the encryption is completed, it drops its ransom note in the form of a small program called “mpsigeng.exe” which contains the following context:

“YOUR FILES ARE ENCRYPTED YOUR FINGERPRINT: [redacted]

SEND 0.01 BTC to address: [redacted]

SEND TRANSACTIONID AND FINGERPRINT to decryptmefinger@gmailcom

YOU RECEIVE DECRYPTION INBOX”

As you can see, based on its ransom note, victims have to pay the demanded ransom, 0.01 BTC to a given Bitcoin wallet address. If you are one of the victims of this file-encrypting threat, paying the ransom won’t get you anywhere and you’ll only end up losing money and still no recovered files. So the best way you can deal with this kind of threat is by obliterating it from your computer first and then try other ways to recover your encrypted files.

How does LittleFinger ransomware spread online?

LittleFinger ransomware spreads via spam emails. These malware-laden spam emails are often disguised to make it seem like it was sent by some well-known individual or company so that you won’t suspect the safety of the file attached. So if you happen to come across such emails, it’s best to stir clear of them rather than get tricked into downloading some obfuscated file used to launch LittleFinger ransomware.
